This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
What is the breaking capacity (Icu) of this breaker?
The breaking capacity class S gives Icu=36kA at 415V AC, which is the maximum short-circuit current the breaker can safely interrupt.
What does the TM240 trip unit setting mean?
TM240 is the thermal-magnetic trip designation. Overload protection (Ir) is adjustable from 56A to 80A, and short-circuit protection (Ii) is fixed at 5 to 10 times the In rating (400A to 800A at In=80A).
